Before using the EZL 300S the user must set wireless LAN related items Wireless LAN related items can be set via ezSerialConfig or console in a Console mode Supply power without the PCMCIA card insertion to enter into Console mode In the Console mode the user can set not only wireless LAN related items but also all setup values of the EZL 300S 2 1 3 Connecting to the Network Insert the PCMCIA card while power is not supplied Then connect the device with the EZL 300S using RS232 cable that is compliant with the specification and supply power After power is supplied the link LED should be turned on When the link LED is on it means that a link has been established between the AP and wireless LAN device or between the wireless LAN devices to enable communication between them 2 1 4 Configuring the Environmental Variables When network connection is completed configure the environmental variables such as IP address related items serial port related items and communication mode related items through the LAN using ezConfig the environmental variable configuration program F For environmental variable configuration see 3 Configuring wireless LAN E IP Address and Environmental Variables 12 2 2 Test Run You can perform test run according to the following orders The test run described here is based on the assumption that the IP address of the PC is set to 10 1 0 2 and its serial interface is configured as RS2
